Caulk Windows

Be sure to caulk around windows and doorframes to prevent heat from escaping. “Caulking and sealing openings is one of the least expensive maintenance jobs,” says Michael Hydeck, Hydeck Design Build, Inc., Telford, PA, and National President, National Association of the Remodeling Industry (NARI). “Openings in the structure can cause water to get in and freeze, resulting in cracks and mold buildup,” he says.
